Caffeic Acid Phenethyl Ester Loaded in Skim Milk Microcapsules: Physicochemical Properties and Enhanced In Vitro Bioaccessibility and Bioactivity against Colon Cancer Cells

Caffeic acid phenethyl ester (CAPE) has various biological activities but low water solubility and poor bioavailability. In this study, CAPE was encapsulated in skim milk powder (SMP) by spray drying warm aqueous ethanol solutions with different mass ratios of SMP and CAPE. The loading capacity and encapsulation efficiency were up to 10.1 and 41.7%, respectively. Differential scanning calorimetry and X-ray diffraction results confirmed the loss of crystallinity of CAPE after encapsulation. Fourier-transform infrared and fluorescence spectroscopy results indicated the hydrophobic binding between CAPE and caseins. Scanning electron microscopy and static light scattering results showed spherical capsules with an average diameter of around 26 mu m. The CAPE loaded in SMP microcapsules showed significantly improved in vitro bioaccessibility and antiproliferation activity against human colon cancer cells compared to free CAPE. The simple, scalable, and low-cost approach in the present study may be significant for industrial encapsulation of CAPE and other lipophilic bioactive compounds.

Synthesis of 4-substituted-3-Hydroxyquinolin-2(1H)-ones with anticancer activity

Herein we show that the 3-hydroxyquinolin-2(1H)-one (3HQ) core is a suitable platform to develop new compounds with anticancer activity against MCF-7 (IC50 up to 4.82 mu M) and NCI-H460 (IC50 up to 1.8 mu M) cancer cell lines. The ring-expansion reaction of isatins with diazo esters catalysed by di-rhodium (II) complexes proved to be a simple and effective strategy to synthesize 4-carboxylate-3HQs (yields up to 92%). 4-Carboxamide-3HQs were more efficiently prepared using NHS-diazoacetate in yields up to 88%. This innovative methodology enabled the construction of peptidic-like 3HQs, with several amino acid substituents. Among this series, the L-leucine derivative induced the cell death of MCF-7 (IC50 of 15.1 mu M) and NCI-H460 (IC50 of 2.7 mu M) cancer cell lines without causing any appreciable cytotoxicity against the non-cancer cell model (CHOK1).

Effects of Glutathione and Histidine on NO Release from a Dimeric Dinitrosyl Iron Complex (DNIC)

Rates of NO release from synthetic dinitrosyl iron complexes (DNICs) are shown to be responsive to coordination environments about iron. The effect of biologically relevant cellular components, glutathione and histidine, on the rate of NO release from a dimeric, Roussin’s Red Ester, DNIC with bridging mu-S thioglucose ligands, SGlucRRE or [(mu-SGluc)Fe(NO)(2)](2) (SGluc = 1-thio-beta-D-glucose tetraacetate), was investigated. From the Griess assay and X-band EPR data, decomposition of the product from the histidine-cleaved dimer, [(SGluc)(N-His)Fe(NO)(2)], generated Fe(III) and increased the NO release rate in aqueous media when compared to the intact SGlucRRE precursor. In contrast, increasing concentrations of exogenous glutathione generated the stable [(SGluc)(GS)Fe(NO)(2)](-) anion and depressed the rate of NO release. Both of the cleaved, monomeric intermediates were characterized with ESI-MS, EPR, and FT-IR spectroscopies. On the basis of the Griess assay coupled with data from an intracellular fluorometric probe, both the monomeric DNICs and dimeric SGlucRRE diffuse into smooth muscle cells, chosen as appropriate archetypes of vascular relaxation, and release their NO payload. Ultimately, this work provides insight into tuning NO release beyond the design of DNICs, through the incubation with safe, accessible biological molecules.

Iodine-Catalyzed Selective Functionalization of Ethane in Oleum: Toward a Direct Process for the Production of Ethylene Glycol from Shale Gas

Direct valorization of ethane, a substantial component of shale gas deposits, at mild conditions remains a significant challenge, both from an industrial and an academic point of view. Herein, we report iodine as an efficient and selective catalyst for the functionalization of ethane in oleum at low temperatures and pressures. A thorough study of relevant reaction parameters revealed iodine to be remarkably more active than the previously reported Periana/Catalytica catalyst under optimized conditions. As a result of a fundamentally different catalytic cycle, iodine yields the bis-bisulfate ester of ethylene glycol (HO3SO-CH2-CH2-OSO3H, EBS), whereas for state-of-the-art platinum-based catalysts ethionic acid (HO3S-CH2-CH2-OSO3H, ETA) is obtained as the main product. Our findings open up an attractive route for the direct conversion of ethane toward ethylene glycol.

A phase 4, randomized, head-to-head trial comparing the efficacy of subcutaneous injections of brodalumab to oral administrations of fumaric acid esters in adults with moderate-to-severe plaque psoriasis (CHANGE)

Background Brodalumab is a fully human monoclonal immunoglobulin IgG2 antibody that binds to the human IL-17 receptor subunit A and by that inhibits the biologic action of IL-17A, IL-17F, IL-17C and IL-17E. Therapy with fumaric acid esters (FAE) is a well established and widely used first-line systemic treatment for subjects with moderate-to-severe plaque psoriasis. Objectives To compare brodalumab to FAE in terms of clinical efficacy, patient-reported outcomes and safety in subjects with moderate-to-severe plaque psoriasis who were naive to systemic treatment. Methods Eligible subjects were randomized 1 : 1 to 210 mg brodalumab injections or oral FAE according to product label in this 24-week, open-label, assessor-blinded, multi-centre, head-to-head phase 4 trial. The primary endpoints were having PASI75 and having sPGA score of 0 or 1 (sPGA 0/1). Subjects with missing values for the primary endpoints were considered non-responders. Results A total of 210 subjects were randomized. 91/105 subjects completed brodalumab treatment and 58/105 subjects completed FAE treatment. At Week 24, significantly more subjects in the brodalumab group compared to the FAE group had PASI75 (81.0% vs. 38.1%, P < 0.001) and sPGA 0/1 (64.8% vs. 20.0%, P < 0.001). In the brodalumab group, the median time to both PASI75 and to PASI90 was significantly shorter than in the FAE group (4.1 weeks vs. 16.4 weeks, and 7.4 weeks vs. 24.4 weeks, respectively, P < 0.0001 for both). The rate of adverse events was lower in subjects treated with brodalumab compared to subjects treated with FAE (616.4 vs. 1195.8 events per 100 exposure years). No new safety signals were detected for brodalumab. Conclusions Brodalumab was associated with rapid and significant improvements in signs and symptoms of moderate-to-severe plaque psoriasis, with a superior efficacy profile to what was observed with FAE in systemic-naive subjects over 24 weeks. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 6065-82-3, in my other articles.

Oxiranyl remote anions from epoxy cinnamates and their application towards the synthesis of alpha,beta-epoxy-gamma-butyrolactones

A series of alpha,beta-epoxy-gamma-butyrolactones were synthesized in moderate yields via oxiranyl remote anions derived from epoxy cinnamate esters. The key synthetic step involved deprotonation of the beta-position of alpha,beta-epoxy cinnamate derivatives where the generated beta-anion was stabilized by remote chelation from an ester group. The substitution reaction of the anion with a variety of ketones, followed by cyclization, readily furnished the desired substituted alpha,beta-epoxy-gamma-butyrolactones. (C) 2020 Elsevier Ltd.

A photocaged inhibitor of acid sphingomyelinase

Acid sphingomyelinase (ASM) is a potential drug target and involved in rapid lipid signalling events. However, there are no tools available to adequately study such processes. Based on a non cell-permeable PtdIns(3,5)P-2 inhibitor of ASM, we developed a compound with o-nitrobenzyl photocages and butyryl esters to transiently mask hydroxyl groups. This resulted in a potent light-inducible photocaged ASM inhibitor (PCAI). The first example of a time-resolved inhibition of ASM was shown in intact living cells.
